<div style="padding-left: 30px;">
    <br>
    In this study, the computer <b>will repeatedly draw poker chips from a digital bag</b> to determine your score (which will determine your bonus). You need to decide for how long you want the computer to keep drawing.     
    <ul>
            <li>
                The bag contains 100 poker chips, each worth a different number of points.
                <ul>
                    <li>
                        The least valuable chip in the bag is worth 1 point and the most valuable is worth 100 points. There is a chip in the bag worth each point value in-between.
                    </li>
                </ul>   
            </li>
    <li>
        Your score (which determines your bonus) is given by
<center>
    <div class="formula_li">
<b>        Score = Highest chip value drawn - Total cost of drawing chips.
</b>
        </div>
</center>
    </li>
            <li>
        The computer will <b>repeatedly draw a poker chip from the bag (replacing the chip in the bag after each draw) until it gets one that is higher than some minimum <b>threshold</b>.</b>  Your job is to tell the computer <b>what you would like this threshold to be:</b>   
        <b>the first chip that the computer draws that is at least as large as the threshold will determine your base score.</b>
    </li>
    <li>
        However, <b>each time</b> the computer draws a chip from the bag, it will <b>charge you some cost that will be subtracted</b> from your base score to determine your overall score. 
    </li>
    <li>
        Your task is to set the threshold. Setting this threshold has two effects: 
        <ul>
            <li>
                First, <b>the higher the threshold you set, the more valuable the chip that will determine your base score, on average.</b>
            </li>
            <li>
                Second, <b>the higher your threshold, the larger the number of times (on average)</b> the computer will have to draw from the bag before getting a chip that is large enough,<b> meaning a higher cost.</b>
            </li>
        </ul> 
    </li>
    <li>
        In each round, <b>you will be told the cost </b>the computer will charge each time it draws a chip from the bag.  You will then decide on the threshold value (between 1 and 100) the computer  uses to stop drawing chips from the bag.
    </li>
    <li>
        In total, you will complete 11 rounds of this task. Across these rounds, the cost charged per draw from the bag varies. These rounds are completely independent from one another. If one of the rounds of this task is selected to determine your bonus, only your decision in this one round will determine your bonus.
    </li>
</ul>

<u>Your bonus payment:</u>
</h2>
<div style="padding-left: 30px;">

        Your decisions in this study may aﬀect your bonus payment. 
        If a decision in this study is selected for payment, 
        you will receive $10 if your decision is within +/- 1 points of the <b>best decision</b> which is the
        <b>threshold
             that leads to the highest score, on average.</b>   
        Specifically, we will have the computer make the full set of draws 1 million times and 
        calculate the average score for every possible  threshold  you could have chose.  
        If the threshold you chose was within +/- 1 points of the choice that maximized the score in these computer simulations, you will earn a $10 bonus.

        This procedure may seem complicated, but it simply means that you should choose the threshold  that you think will earn you the highest score, on average.
            <!-- 


    Your decisions  may affect your bonus payment.  
    If a decision in this study is selected for payment, you will 
    <b>earn a number of points equal to the final poker chip drawn by the computer, minus the total cost from the number of draws taken by the computer.</b>  
    You will earn $0.10 for each resulting point (there is no chance of losing money based on your choice).  
    <b>Instead of calculating this once, we will have the computer make the full set of draws 1 million times, 
        and pay you your average earnings over all of these repetitions of the problem.  
        This means there is no risk in this study and also that the decision that maximizes the average earnings also maximizes your bonus.</b>

            In this example, the computer will charge you 3 points every time it draws a poker chip from the bag.
        </li>
        <li>
            You then need to decide on the threshold, between 1 and 100, that the computer should use to stop drawing chips from the bag.

   <u>Your certainty:</u>

<div style="padding-left: 30px;">
   <br>
   In each round, we will ask you two questions:
    <br>
   <ul> 
       <li>
        You will decide on the threshold the computer can use to stop drawing chips from the bag.

    </li>
       <li>
        We will ask you <b>how certain</b> you are about your decision. Specifically, we are interested in how likely you think it is (in percentage terms) that the decision you made is actually the best decision, by which we mean the decision that maximizes your bonus.    </li>
